2005-08-08 Matthias Clasen <mclasen@redhat.com> * tests/convert-test.c: Enable the endianness test. * glib/gconvert.c: Make the caching of iconv descriptors optional. * configure.in: Add an --enable-iconv-cache option, and default to disabling iconv caching on new enough glibc. Somebody with access to Solaris systems will need to test if opening/closing of iconv descriptors is enough of a performance problem to warrant the caching on that platform. Note that the caching is causing correctness problems in some corner cases, thus turning it off is desirable unless it has severe performance implications.
